Perl sizeof Equivalent

jeffthewookiee has asked for the wisdom of the Perl Monks concerning the following question:

I'm working on a pretty memory intensive Perl script, using a lot of nested hashrefs and arrayrefs. I need to be able to compare the size of different data structures. Is there anything like a C sizeof operator for Perl that I can use to estimate memory usage?

Others will give you the answer you're looking for. I'm here to recommend using DBM::Deep for some of these structures. My criteria for good software: Does it work? Can someone else come in, make a change, and be reasonably certain no bugs were introduced?	[reply]
